Application died March 1 To all whom may concern:

Be it known that WALTER Iii. Dunn acitizen of the United States and aresident or" lii illrinsbur in the county of Allegheny and State ofZ'ennsylvania, have invented a new and useful improvement in TransformerRadiators, of which the following, is a specification.

invention relates to heat-dissipating devices and it has peculiarrelation to apparatus oi the above designated character that isparticularly adapted for use in connection with electrical or otherapparatus adapted to be immersed within a cooling fluid. Morespecifically, my invention relates to means for cooling the oil or otherfluid used in transformers and to the construction oi such means Oneobject of my invention is to provide aradiator of novel type having arelatively radiating; area, as compared with the quantity oi coolingtherein.

Another obiect my invention is f m radiators shall be light in weig andinexpensive in manufacture and we designed to withstand considerablewithout deformation. is ie speaking n invention comprises constructingtheside walls, the top and bottom members and the end walls of separatemembers which are welded together after being assembled.

llereto'iore it has been customary to con: struct radiators of spacedtanks or headers and a plurality of spaced tubes disposed intermediate,and communicating with said headers. lihe objection to such. structuresis that dead air spaces of substantially pyramidal shape are forme ofwhich the inner surfaces of the headers constitute the bases.

According to my invention, my radiator comprises a vertically extendingcentral chamber having a plurality of ofi'set chambers radiatingtherefrom. The offset portions are formed by the side walls whichconsists of a plurality of segments of substantially ti-shape joinedtogether in side by-side relation. Each of the top and the bottomenclosing members of the central vertically-extending chamber is ofsubstantially Ushape. The ends of the radiator are closed by separateend members welded to the ends Z, 1921. Serial N0. 452,35?

of the side walls and to the ends of the top and bottom members.

In the accompanying drawings, Figure l is a plan =view of a radiatorconstructed in accordance with my invention.

Fig. 2 is a'view, partially in end elevation and partially in section,0% the structure shown in Fig. l, the sectional portion oi this figurebeing taken along; the line HH of Fig. 1.

Fig 3 iso perspective view of certain of the members embodied in aradiator constructed in accordance with my invention. According to myinvention a radiator comprises a top member 4i and a bottom memher 5joined together at the sides by walls 6 and 'Z and at the ends by endmembers 8 and 9. Each of the members 4- and 5 consists of a pressedmetal part of substantially U- shape which constitutes the top and thebottom, respectively, of a vertically-extending fluid chamber 10.

Each of the side walls 6 and 7 comprises a plurality of pressedmetalmembers 11 of substantially U-shape,.as best shown in Fig. 8. F or thesake of clearness, but two such members are shown on each side. Each ofthe members 11 consists of a base portion 12 and two integral sideportions 13 of substantially dish-shape. The base portion 12 is weldedat the-top and at the bottom to the members 42 and 5, respectively. Theedge of each of the side portions 18 is adapted to engage the edge ofthe side portion oi the next adjacent member 11. .This forms a flatmetallic envelope having an open side which is in communication with thecentral chamber 10.

Each of the side members 13 is provided with extruded portions 1% toengagesimilar portions extending from the other integral portions 13which constitutes one wall of the next adjacent fluid chamber.Distortion of the walls by the pressure of the fluid within the members11 is thereby prevented. Each-of the twocoacting portions 13 of adjacentunits 11, which cooperate to form a radiating chamber is provided withan outwardly projecting flange 15 which is welded to a similar coactingflange 15 oi the next adjacent portion 13.

Each of the end members 8 and 9 is of -with a flange 17 of similarcontour to the proper operative positions.

flange 18 of the member 16, to which it is welded. A plurality ofextruded vertical ribs 19 serve to reinforce the end members 8 and 9. Aplurality of tie-bolts 20, extending through the end members 8 and 9 andthe vertical chamber 10, serves to support the entire radiator and toadd to its rigidity and strength. Bracing members 21 are disposed at theends of the bolts 20 to engage the end members 8 and 9. Each of the endmembers 8 and 9 is provided with oflset integral projections 22 at thetop and bottom thereof which serve as closures for the ends of the topand bottom members 4 and 5, respectively, and are provided with flanges23 which are welded to said members.

The radiator may, if desired, be constructed b first assembling" aseries of units 11 in si e-by-side relation and welding together theiradjacent flan es 15. The end members 8 and 9 may then e welded to theend sections 16 of the assembled units, and the tiebolts 20 and braces21 be disposed in their The top and the bottom members 4 and 5,respectively, may then be placed in position, being welded tothe ends ofthe base portions 12 of the side members 11 and to the flanges 23 of theoffset portions 22 of the end members 8 and 9. I

The ofiset portions 22 of the member 8 are provided with apertures 24 bymeans of which communication is established with a tank or othercontainer, not shown. The pipes associated with the apertures 2 L alsoserve as supports for the radiator.

From the foregoing description, it will be apparent that I have produceda radiatorof novel-type, that is light in weight, simple and inexpensivein manufacture, and durable in operation. Also, -it is apparent that, ina structure manufactured in accordance with my invention, a freecirculation of air in a vertical direction between the various sectionsis facilitated by reason of the straight walls thereof.
